For a more 'complet e disclosure of the adding equipment refereiTce ismade to Patents' Nos. 825,469 to Laganke' and Smith, 825,494; to JohnA.- Smith, 829,791 to Lagankemnd Smith and to the co-pending applicationof Laganke and Smith No. 308,279.

Each of the registers? includes, as usual, what is known as therestoring slide '10 which, when moved back, eflects the resetvtingofthecarrying mechanism. So far 4 causing thebar 12 by coagtion with the pinsas the register is concerned, the present invention contemplates noexchange except that the restoring slides 10 insteadof hav ingtheir'front ends extended beyond the front of the registers for'coaction with a ca'in on the carriage, are each provided with adependent pin 11 dropped suiliciently below the bottom of the registerto coact with the universal'restoring bar 12 of a restoring yoke 13carried by bracketsl lsecured to the register supporting bar 6 as byscrews or other suitable securing devices 15. The restoring yoke 13includes, besides the bar 12, a pair of side members 16 of angular orbell-crank form pivoted at their angles to the brackets 14.

Extended between the ends of the member 16 remote from the bar 12 is asecond transverse .bar 17 having connection with a rest-oring motor 18adapted when operated to, swing the yoke 13 for the purpose of 411 tooperate the'slides 10 of the registers in order to restore the carryingmechanism thereof. In,its.,broader aspects it is immaterial whatcharacter of motor is employed for this purpose. In the presentdisclosure the ,motor 18 is in the form of a solenoid, the core orarmature ,19 of which is formed at its upper end with a book 20 engagingthe bar .17 and provided'at its lower end with a switch member orcircuitcontrolling device 21.. Encircling. the core 20 between the switchmember 21 and the body portion of the solenoid is a "spring 22 whichcompels the retraction of the armature or core 19 when the solenoid isdeenergized. 23- -23 indicate the terminals ot the solenoid-windingwhichare equipped with binding posts 24 for the attachment of the line wiresa and 5 leading to a battery or other suitable source ofelectrical'energy c. The motor 18 is mounted on abracket 25 screwed orotherwise secured to the main frame of the machine, as shown in Fig. 1.It will now be fseen that ifthis circuit, including the battery: andsolenoid, is cl0sed,the latter will be energized and the armature 19thereof will rise against the resistance of the spring 22 therebyswinging the restoring yoke 13 and simultaneously restoring thevcarrying mechanisms of all the registers. As soon, however, as thearmature 19 reaches the limit of its upward movement, the switch member21 will engage and span the inter.- val between the terminals 23 thusshortcircuiting the current and de'energizing the solenoid, the springimmediately retracting the parts to normal position.

Located in the motor circuit is'a circuit closing device 26 which may beand preferably is mounted on one of the carriage stops 2( which areordinarily adyustably mounted on the frame of themachine and are set toarrest the carriage at any desired limit of movement. The circuitclosing device 26 comprises two terminals 26 and 26 suitablv insulatedfrom the stop 27 and arranged to be spanned. by one end of aspringretracted plunger 26 likewise mounted on but insulated from thestop 27. This circuit closing device is adapted to be manually operatedsince the operator may at any time press theplunger 26" into contactwith tirly independent of the carriage and may be effected regardless ofthe particular location of the carriage on the frame. It is intended,howeyer, to provide for boththe manual and automatic control of the re:

storingmeehanisnrso that, while the latter may be rendered active at anytime, regardless of the position of the carriage, it will also bebrought into action automatically when the carriage reaches a givenposition, preferably when the carriage is retracted to begin a newlineof writing.

To accomplish this automatic control the arm or brac'ket28 usuallyextended from the left hand end of the carriage to engage the carriagestop 27 is provided with a pivoted plunger-operating member 29 disposedin line with the plunger 26 of the circuit closing device 26. Thus whenthe carriage ofthe typewriter is retracted the member 29 will contactwith the plunger 26 urging the latter between the teri'niii'als 26'" and26 and closing the. circuit. Obviously, the particular point in theretractile move.- ment of the carriage at which the operation of therestoring mechanism shall take place may be regulated by the adjustmentof the s'top27 upon the frame in the usual manner.

The mechanism as thus far described'is entirely effective because thecircuit will be ture of-which, upon the complete actuation- :meeeee athe right the member 29 will swing back to nermei pesition for arepetition of the detreelen scribed. peretion when the carriage is againa the retreat ft I ithen it. is net etesired that the eelriege An. shalteutematlcally effect the openmg as Me .3 11 as the elesmg oi the clrcultdurmg 1ts s-ers ere e-e-' l'et e? reetile mevement, it is merelynecessary the resisten (May to reme-ve the pm 31, m- Whleh event the.sezzzmates the aefy 3' 0,.
